Abstract
The work demonstrates the results of quantum chemical calculations of 19F and 13С NMR spectra of model fluorocarbon C n F2 n +2 molecules with various configurations and hydrocarbon chain molecules. The possibilities to determine the chain length, formation of branches, identification of fluorine substitution for hydrogen during the fluorination of hydrocarbon paraffins and polymers are discussed.
